IDOFFER-GUARD AND OIL-WELL COVER FOR SPINDLE-SUPPORTS FOR SPINNING ANDTHE LIKE MACHINES.

To all whom it may concern:

Be it known that I, ALBERT H. MORTON, of Lowell, in the county ofMiddlesex and the Commonwealth of Massachusetts, have invented certainnew and useful Improvements in Dofl'er-Guards and Oil-Well Covers forSpindle-Supports for Spinning and the Like Machines, of which thefollowing description and claims, with the accompanying drawing, is aspecification.

My invention relates to dofier-guards and oil-well covers forspindle-supports of spinning, twisting, and the like machines; moreparticularly to such guards-and-covers as are pivotally mounted upon anoil-well post.

The invention consists essentially in the combination in a new articleof manufacture, in one piece of substantially uniform thicknessthroughout, of a doflier-guard, an oil-well cover, and a flange commonto the guard and the cover and constructed for pivotal mounting upon anoil-well post.

It also consists in the combination of the article with an oil-well postconstructed to receive it and means for pivotally mounting the guard andcover upon the post.

In the drawings of the preferred form of my invention: Figure 1represents in sideelevation the spindle, the spindle-support, and thearticle pivotally mounted thereon; Fig. 2 represents inlongitudinal-section, through the axes of the oil-well post and thespindle, the upper portion of the post with the article pivotallymounted thereon and indicates by dotted lines the operative, position ofthe spindle-whirl and a part of the spindle-support; Fig. 3 is a partialsideelevation of the post as seen when looking from the spindle, andshowing the form of the lug upon which the guard-and-cover is mounted;Fig. 4 represents the article without the post projected upon a planeparallel to the top of the post; Fig. 5 represents the top of the postprojected upon a plane parallel thereto, but not showing parts lowerthan the top; and, Fig. 6 represents a vertical section as seen whenlooking toward the spindle, and showing the article, the lug, and thepivot.

projection 2 for preventing Patented Mar. 28, 1911. Serial No. 589,542.

Similar numerals refer throughoutthe views.

In the drawings: 1 is the oil-well post on the bolster case, 2 is thepivot-lug or hinge projection near it top horizontally perforated at 3for the pivot-pin 4c.

5 is the oil-well cover. It closely fits and covers the top of the postand its pivotlug 2.

6 is the doffer-guard, preferably a plane surface, and, when in positionwith the cover closed upon the oil-well, preferably inclined downwardlyand toward the spindle 7.

8 is the flange common to the guard and the cover and preferablydownwardly turned and perforated at 9 9 for the pivotpin 4:. This flangeis in one piece with the doffer-guard and oil-well cover, givesstrength, stability, and stiffness to the article near the pivot and,preferably to the entire article, and is well adapted to be perforatedfor the pin 4. The inner surface 10 of the doft'er-guard constitutes astop for contacting with the stop 11 of the lug or to similar parts thecover through more than a predetermined angle.

The article comprises, in combination, a substantial interior body ofsteel and a superficial film comprising chemically combined iron andoxygen which is not rust and which prevents rust. Preferably, the filmis blue but it may be purple, black, or other color and produced by anywell known process.

I claim:

1. A spindle for spinning and the like machines, comprising incombination, a spindle, a bolster case provided with an oilwell posthaving a hinge projection on the side toward the bolster case and acombined oil-well cover and dotter-guard extending over the uppersurface of the oil-well post and projection and beyond said projectiontoward the bolster case to act as a dofierguard and having its edgeextending downward to embrace the sides of the projection and form pivotpin ears and dofier-guard reinforcement.

the raising of 2. A spindle for spinning and the like machines,comprising in combination, a spindle 2t bolster case provided With anoilweii post having a hinge projection on the side toward the bolstercase, and a combined oil-Well cover and doffer-gnard extending over theupper surface of the oil-Well post and projection and beyond saidprojection toward the bolster case to not as a doflerguard and providedWith Webs or flanges 10 uniting the dofier-guard portion and the topportion to strengthen the doffenguard.

In testimony whereof, I nflix my signature in the presence of twoWitnesses.
